I got my RO
from Aquasafe Canada and I bought the pump at the same time from them. I would check around though.
I tried to add a kill switch from AquaFX to stop the pump when a certain pressure was seen and I never could get it to work. I have seen boosters sell pretty cheap on Ebay sometimes too.
I think my pressure was no more than 30. I could leave it on all night and not fill a 5 gal
jug. It takes a few hours now to fill it.
